Riverside County SWAT officers arrested a man Wednesday morning after an eight-hour standoff on the Morongo Indian Reservation.

Sheriff’s deputies and Morongo Tribal Patrol officers responded to reports of gunfire in the 48000 block of Morongo Road just before 7 p.m., according to a sheriff’s report.

Authorities said a man inside a home on the reservation came outside and started shooting a pistol. A man inside the home made multiple 911 calls that someone was shot, but repeatedly hung up and refused to offer details.

Sheriff deputies and tribal officers evacuated nearby homes and closed several streets while searching for anyone who might be injured. During a sweep of the area, a loaded gun was found outside the home. No one injured was found.

A SWAT team and a Crisis Negotiations Team responded to the area and made several tries to reach the man inside. A SWAT team raided the home just before 4 a.m.

The man arrested refused to identify himself to police, other than he was not a Morongo tribal member.
